... 9. Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial. Round to the three decimal places. n = 4, x = 3, p = 1/6 Ans. 0.015 Find the ind ...
